adding zero column to matrix

Hi All,

Currently I'm facing an error with a Matlab code.

In my problem I have Two matrix v and stateHit

v =

 0.0044    0.1620    0.0272    0.0029    0.1610    0.6035    0.0151    0.0239
 0.0044    0.1639    0.0275    0.0029    0.1606    0.6019    0.0150    0.0238
 0.0043    0.1657    0.0279    0.0030    0.1601    0.6002    0.0150    0.0238

stateHit =

     1     0     0     0
     1     0     0     0
     1     0     0     0

I want to do

difMatrix= v(1:length(stateHit),:) - cpustateHit;

??? Error using ==> minus Matrix dimensions must agree.

I want add zero columns to stateHit.

Could please give an example how can add zero columns to stateHit so that matrix dimension of v and stateHit became the same and I do that operations

difMatrix= v(1:length(stateHit),:) - cpustateHit;

many thanks in advance

SM

Hi,

if it's just that you want to enlarge "stateHit", you could do

if size(stateHit,2)<size(v, 2)
  % v has more columns
  stateHit(1, size(v,2)) = 0;
end

Hi Titus,

Thanks you very much, it works nicely
